000008872 520__ $$2eng$$aWe consider acoustic wave propagation in waveguides which are equipped with perforated plates in a form of single or multi-plate panels. Recently we developed mathematical models of the acoustic or vibro-acoustic interaction on such perforated structures using the method of homogenization. These models describe transmission conditions imposed on flat interfaces representing the panels in the global acoustic problems. In view of vast application in the structural optimization, we developed the sensitivity analysis of the acoustic fields with respect to the perforation design. In this paper we report on methods of modeling and optimization of the waveguides designed by the shape, position of the panels and their design.
